Sposób wykonania emblematu tekstylnego polega na tym, że na powierzchnię elementu z materiału włókienniczego (1) tkanego lub dzianego, z włóknami syntetycznymi w jego strukturze, zespolonego z podłożem z materiału włókienniczego nietkanego (2), zwłaszcza fizeliną, który jest napięty na specjalną ramę do haftowania, nanosi się, korzystnie maszynowo, wzór haftu wewnętrznego (4). Następnie stronę spodnią znanym sposobem zespala się z kolejną warstwą materiału nietkanego (3). W kolejnej operacji emblemat przemieszcza się mechanicznie względem igły głowicy maszyny haftującej wzdłuż linii zadanego, korzystnie programem komputerowym, konturu kształtu emblematu, zaś igła głowicy maszyny ściegiem hafciarskim obszywa brzeg emblematu. Ostatnią czynnością jest odcięcie naddatku materiału włókienniczego. Czynność tę wykonuje się za pomocą narzędzia, którego element tnący jest podgrzany do temperatury topnienia włókien syntetycznych zawartych w strukturze materiału włókienniczego emblematu.

Title: Film web, window frame provided with a web of this type and use of said web
Inventor: WELTER WERNER
IPC: E04D12/00
Filed: 2000-11-03
Abstract: The invention relates to a multi-layer film web with a configuration which ranges from being open to diffusion to preventing diffusion (4, 4a) for use in the construction industry. Said web has a central layer consisting of a water and air-tight plastic and external layers which can be cleaned consisting of non-woven or woven fabric, technical warp-knitted fabric, knitted fabric, glass fibre, reinforced paper, film or similar and a self-adhesive layer on the edge. The width of the film web (4, 4a) measures between 5 and 80 cm. The thickness of the film web and the type of the adhesive, in addition to the width (c) of the self-adhesive layer are matched in such a way that the film web (4, 4a) can be fixed purely by adhesion without any form of mechanical fastening, in a permanent manner to plastic, aluminium, wooden or similar window sections (1) and/or to conventional water-vapour resistant films (12) consisting of polyolefins or similar. An absolutely air and wind-tight connection can thus be achieved on the building site at minimum cost, with the connection zone allowing the diffusion of water vapour, or having increased water-vapour resistance, depending on the type of film selected, than can be achieved with prior art.
